Abstract :
A need exists for a monitor for use in plastic surgery. We have developed an inexpensive device which uses a modified pulse oximeter probe to measure changes in concentration of haemoglobin species in free flaps during surgery. Reperfusions of free flaps have been monitored and initial results show a marked difference in response between healthy and failing flaps
